Description

Technical Field

[0001] This utility model belongs to the field of brake caliper technology, and relates to a guide pin, particularly a guide pin for brake calipers. Background Technology

[0002] Since the brake disc of a car rotates while the vehicle is in motion, the brake is needed to slow down, stop, or keep the moving parts in a stopped state. In automobiles and other vehicle devices, the braking mechanism generally adopts the disc brake mechanism, which has the following main structure: the brake disc is fixed on the wheel axle, and a hydraulic clamping device is provided at the edge of the brake disc. When braking, the friction pads in the clamping device are clamped to the brake disc by the hydraulic system, and the brake disc decelerates quickly under the action of friction.

[0003] In real-world use over a long period, the grease inside the brake guide pin of the brake caliper will disappear, causing rust to form on the guide pin and resulting in braking problems on the car's brake disc. When it is necessary to maintain the guide pin or replace the brake pads, the fixing bolts need to be turned to loosen them, making brake disc maintenance inconvenient. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a maintenance-friendly guide pin for brake calipers.

[0005] The objective of this utility model can be achieved through the following technical solution: A guide pin for a brake caliper, comprising a caliper body, a brake pad, and a bracket, characterized in that guide pins are provided at both the upper and lower ends of the bracket, the bracket has a mounting hole I for installing the guide pin, the guide pin is composed of a floating pin and a fixed pin, the floating pin has a mounting hole II for installing the fixed pin, the caliper body has a connecting hole for the fixed pin to pass through, a snap-fit ​​mechanism is provided on the floating pin and on the inner wall of the mounting hole II, the floating pin has a movable space I for the snap-fit ​​mechanism to move, the snap-fit ​​mechanism includes a snap-fit ​​block and a snap-fit ​​spring, the front end of the fixed pin has a snap-fit ​​part for cooperating with the snap-fit ​​block, and an unlocking element is movably provided between the fixed pin and the connecting hole.

[0006] In the aforementioned guide pin for a brake caliper, a locking mechanism is provided at the rear end of the fixed pin. The fixed pin has an active space for the locking mechanism to move. The locking mechanism includes a locking block and a locking spring.

[0007] In the aforementioned guide pin for a brake caliper, the locking block is provided with a guide portion.

[0008] In the aforementioned guide pin for a brake caliper, a limiting protrusion is provided on the bottom of the mounting hole, and a limiting groove is provided on the fixing pin to cooperate with the limiting protrusion.

[0009] Compared with the prior art, the locking mechanism of the fixed pin and the snap-fit ​​mechanism of the floating pin of this utility model can quickly fix the clamp body and the bracket. When disassembling, first press the locking mechanism into the fixed pin and then insert the locking part. By pressing the locking part, the locking part passes through the guide part of the snap-fit ​​block and presses the snap-fit ​​block into the movable space. Finally, the fixed pin and the unlocking part are taken out together to complete the disassembly, thereby realizing the quick replacement of brake pads and the quick maintenance of guide pins.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1As shown, the guide pin for the brake caliper includes a caliper body 1, a brake pad 2, and a bracket 3. Guide pins 4 are provided at both the upper and lower ends of the bracket 3. The bracket 3 has a mounting hole 5 for installing the guide pin 4. The guide pin 4 consists of a floating pin 6 and a fixed pin 7. The floating pin 6 has a mounting hole 8 for installing the fixed pin 7. The caliper body 1 has a connecting hole 9 for the fixed pin 7 to pass through. A locking mechanism 10 is provided on the floating pin 6 and on the inner wall of the mounting hole 8. The floating pin 6 has a movable space 11 for the locking mechanism 10 to move. The locking mechanism 10 includes a locking block 12 and a locking spring 13. The front end of the fixed pin 7 is provided with a locking part 14 for cooperating with the locking block 12. An unlocking element 15 is movably provided between the fixed pin 7 and the connecting hole 9.

[0016] To elaborate further, a locking mechanism 16 is provided at the rear end of the fixed pin 7. The fixed pin 7 has an active space 17 for the locking mechanism 16 to move. The locking mechanism 16 includes a locking block 18 and a locking spring 19.

[0017] To elaborate further, the snap-fit ​​block 12 is equipped with a guide section 20 for easy installation and unlocking.

[0018] To elaborate further, a limiting protrusion 21 is provided on the bottom of the mounting hole 5, and a limiting groove 22 that cooperates with the limiting protrusion 21 is provided on the fixing pin 7 to reduce the possibility of radial movement of the fixing pin 7.

[0019] Working principle: During installation, push the fixing pin 7 into the correct position. The fixing pin 7 is pressed into the movable space 11 through the guide part 20 of the snap-fit ​​block 12 until the snap-fit ​​part 14 passes through the snap-fit ​​block 12. The snap-fit ​​block 12 then loses its constraint and automatically resets, thus snapping the snap-fit ​​part 14 into place, completing the installation. During disassembly, first press the locking mechanism 16 into the fixing pin 7, then insert the locking component. By pressing the locking component, the locking component passes through the guide part 20 of the snap-fit ​​block 12, pressing the snap-fit ​​block 12 into the movable space 11. Finally, the fixing pin 7 and the unlocking component 15 are pulled out together to complete the disassembly. This allows for quick replacement of the brake pads 2 and quick maintenance of the guide pin 4.

[0020] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0021] Although this document frequently uses terms such as clamp body 1, brake pad 2, bracket 3, guide pin 4, mounting hole one 5, floating pin 6, fixing pin 7, mounting hole two 8, connecting hole 9, snap-fit ​​mechanism 10, movable space one 11, snap-fit ​​block 12, snap-fit ​​spring 13, snap-fit ​​part 14, unlocking part 15, locking mechanism 16, movable space two 17, locking block 18, locking spring 19, guide part 20, limiting protrusion 21, and limiting groove 22, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
